Abstract
The invention relates to a fastener, in particular to a screw fixedly-locking device suitable for light-load fastening products. The screw fixedly-locking device comprises a screw, a nut and a fixed support, wherein a piece to be fixed is fixedly locked on the fixed support by means of the screw and the nut; the screw is provided with non-return threads; the nut is provided with an elastic sheet nut; the elastic sheet nut is fixedly connected to the fixed support; and the screw passes through the fixed support and is inserted into the elastic sheet nut. According to the screw fixedly-locking device, the screw can be arranged on the piece to be fixed in advance, the piece to be fixed is aligned with an assembly position during construction operation, can be assembled if the screw is pressed down and is locked if the screw is rotated. The screw fixedly-locking device is simple, convenient, firm and reliable in the whole assembly process.
Description
Affiliated technical field
The present invention relates to a kind of fastening piece, particularly a kind of screw rod fixing and locking device that is applicable to the fastening product of light load.
Background technique
, we have many installation puzzlements at present in living, work; For example in the installation of the fastening product of some light loads; Existing fastening means commonly used is thread or employing screw buckle normally; The operation process that these fastening means are is loaded down with trivial details (need setting tool and installation efficiency not high) particularly at suspension or high-altitude construction operation, tends to occur in a rush situation.Therefore, selecting a step property completion installation exercise or a construction free-hand and can be simple, quick and easy for use, is that everybody is desired.
Summary of the invention
The object of the present invention is to provide a kind of screw rod fixing and locking device that is applicable to the fastening product of light load, this apparatus structure is simple and reliable, it is extremely convenient to install and use.
The object of the invention is able to solve through following technical proposals:
A kind of screw rod fixing and locking device of the present invention comprises screw rod, nut and fixed support, screw rod and nut with the fixture fixing and locking on fixed support.Described screw rod adopts the non-return screw thread; Described nut adopts the shell fragment nut, and the shell fragment nut is fixedly connected on the fixed support; Screw rod passes fixed support and inserts the shell fragment nut.
The ratio of the tooth top footpath D of described screw rod and the shell fragment thickness t of tooth root dia d and shell fragment nut is (D-d)/2t=1 ~ 2.
The stroke H of described screw flight Rotate 180 ° and the ratio of tooth root dia d are H/d=0.175 ~ 0.571.
The ratio of the shell fragment thickness t of the length of straight flange K of described shell fragment nut and shell fragment nut is K/t=8 ~ 32; The length of straight flange direction of shell fragment nut and screw rod axial angle M=120 ° ~ 160 °.
Tooth root dia d=1.8 ~ the 10mm of described screw rod.
Screw rod fixing and locking device of the present invention can be installed in screw rod on the fixture in advance, and during construction operation, fixture is aimed at the mounting point, presses screw rod and can realize installing, turn screw rod locking again.The whole erection process is not only simple and convenient but also solid and reliable.
Description of drawings
Fig. 1 is a fixing and locking schematic representation of apparatus of the present invention.
Fig. 2 is a fixing and locking schematic representation of apparatus of the present invention.
Fig. 3 is the schematic representation of typical application assembling of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment screw rod fixing and locking device of the present invention is described further:
Like Fig. 1,2,3, shown in 4, a kind of screw rod fixing and locking device of the present invention comprises screw rod 1, nut 2 and fixed support 3, screw rod 1 and nut 2 with fixture 5 fixing and lockings on fixed support 3.Screw rod 1 adopts the non-return screw thread; Nut 2 adopts shell fragment nut 2, and shell fragment nut 2 is fixedly connected on the fixed support 3; Screw rod 1 passes fixed support 3 and inserts shell fragment nut 2.
The ratio of the tooth top footpath D of screw rod 1 and the shell fragment thickness t of tooth root dia d and shell fragment nut 2 is (D-d)/2t=1 ~ 2.
Stroke H that the screw thread rotation of screw rod 1 is 180 ° and the ratio of tooth root dia d are H/d=0.175 ~ 0.571.
The ratio of the shell fragment thickness t of the length of straight flange K of shell fragment nut 2 and shell fragment nut 2 is K/t=8 ~ 32; The length of straight flange direction of shell fragment nut 2 and screw rod 1 axial angle M=120 ° ~ 160 °.
Tooth root dia d=1.8 ~ the 10mm of screw rod 1.
Typical application assembling of the present invention (installation) figure according to accompanying drawing 3 mainly comprises screw rod 1, shell fragment nut 2, fixed support 3, locking back-up ring 4 and fixture 5.Adopt locking back-up ring 4 to be installed in screw rod 1 on the fixture 5; Shell fragment nut 2 is fixedly connected on the fixed support 3, when fixture 5 aligning mounting points, gently screw rod 1 is pressed in the shell fragment nut 2 on the fixed support 3; Screw; Just accomplish assembling, promptly under the guiding of the elastic force of shell fragment nut 2 and structure, realized light, quick, easy installation.When we need open fixture 5 and fixed support in 3 minutes, we only need turn screw rod 1, just can take off fixture 5 as common field-strip.
Screw rod fixing and locking device of the present invention can be installed in screw rod on the fixture in advance, and during construction operation, fixture is aimed at the mounting point, presses screw rod and can realize installing, turn screw rod locking again.The whole erection process is not only simple and convenient but also solid and reliable.
Screw rod fixing and locking device of the present invention can be installed in screw rod on the fixture in advance, and during construction operation, fixture is aimed at the mounting point, presses screw rod and can realize installing, turn screw rod locking again.The whole erection process is not only simple and convenient but also solid and reliable.
Although it is pointed out that here fixing and locking device of the present invention has been carried out detailed description, this with regard to related domain staff, the similar modification of making on this basis of class Sihe all should belong to protection domain of the present invention.
